IMPROVEMENT IN LANTERNS. v

Specification forming part of Letters Patent No. 38,355, dated April 28, 1863.

170 all whom it may concern:

Be it known that I, CHARLES DEAVS, of the city, county, and State of New York, have invented a new and Improved Lantern; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figures 1 and 2 are elevations of my invention Fig. 3, a horizontal section of the same, taken in the line was, Fig. 2 Fig. 4, a diagram showing the way in which the metal portion of the case is constructed.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a lantern of simple and economical construction, which will not be liable to break or get out of repair, and which will, in case of the breaking of a lightor side of glass, admit of one'being readily put in by any person of ordinary ability. The lantern at the same time being portable, and provided with reflectors.

The invention consists in constructing the case or body or the lantern of one piece of sheet metal, so cut or shaped that it may be bent to form the top and two side pieces of the case or body, the side pieces being swaged so as to form reflectors, and the case or body attached to the lamp by means of hinges or joints so arranged as to admit of the case or body being readily turned over to expose the lamp, for the purpose of lighting or trimming the wick of the same.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the lamp of the lantern, which is of rectangular form, and of any suitable dimensions.

B is the burner of the lamp, which is fitted to the center of its top part. This burner may be constructed with a view to the burning of coal-oil, any proper one of the kind being used for that purpose.

0 represents the case or body of the lantern, which is composed of sheet metal and glass. The sheet-metal portion is formed principally of one piece cut in the form, as shown in Fig.

4, a a representing the portions designed for two sides of the case, and b the portion designed for the top part. The two portions or a sides of the case or body 0. The glass plates are retained in position by punching the parts a a at their upper and lower parts to form cleats f, which are bent inward to lap over the edges of the glass, as shown in Fig. 3, the holes formed by the bending inward of the cleats admitting air into the case or body 0 to feed theflame. The lower end of the case or body 0 is equal in dimensions to the upper end of the lamp A, and is connected to the lamp at each end of its top part by a hinge or joint, D, the pintles of which are removable, so that either end of the lower part of the case or body may be liberated, when necessary, to admit of the case or body being turned over on either hinge or joint. (See red outline in Fig. 1.) This turning over of the case or body A exposes to the burner of the lamp,

so that the wick may be lighted or trimmed,

and the lamp filled, when necessary, with the greatest facility. The portion b of the sheetmetal part of the case or body is of such a form as to admit of being turned down at its ends, as shown at g, the upper ends of the glass plates 0 resting against the parts 9.

E represents a cap-piece, which is formed out of a circular piece of sheet metal, bent in arch form, and secured by pins 71. to two opposides sides of the case or body 0. The cap-piece covers an opening, M, in the part b of the sheet-metal part of the case or body. These pins are formed at the upper ends of rods F, the latter being bent, so that-the pins may pass through the cap-piece E, and so as to form eyes i, in which the bail or handle G is fitted. The rods F are secured at their lower ends to the centers of the cross-bars c c, and said rods form guards for the glass plates 0 e, as shown clearly in Figs. 1 and 2.

The parts a a of the sheet-metal portion of the case or body A, are swaged, so as to form oblique or beveled surfaces j j, as shown in Fig. 3. These beveled surfaces serve as reflectors, and throw the rays of light, which strike against them through the glass plates 6 e, as indicated by the red lines in Fig. 3. These reflectors compen sate,in a great degree, for the opaqueness of the sheet-metal sides a a. This lantern maybe constructed at a very small cost, and in case of either of the glass plates 6 6 being broken a new one may be readily inserted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The ease or body 0 of the lantern, formed of the glass plates 6 e, and a sheet-metal portion, so cut or shaped as to form, when bent, two sides, a a, and the top I) of the case or body, the lower ends of the sides being connected by cross-bars c c, substantially as set forth.

2. The combination of the case or body 0,

described.
